The processor executes various functional applications and data processing by running the software programs and modules stored in the memory 120. The memory 120 can be a high speed random access memory, a non-volatile memory, etc., such as a magnetic memory device, a flash memory, or other non-volatile solid state memories.

In some embodiments, the first terminal device 100 can include more or less components, for example, the first terminal device 100 further includes a communication module connected with the processor and configured for communication between the first terminal device 100 and other devices. The second terminal device 200 can have same or similar components as the first terminal device 100, and is not repeated here.

When the first terminal device needs to display virtual content of other terminal devices and virtual content corresponding to the first terminal device, a marker can be used as a reference object so as to obtain the position where virtual content of other terminal devices needs to be displayed. The first terminal device can perform image capture for a marker in its visual range through a camera, and perform identifying and tracking for the marker in images to obtain first spatial position information of the first terminal device relative to the marker. Wherein, the first spatial position information includes position and pose of the first terminal device relative to the marker, the pose includes orientation information and rotation information.

Specifically, model data of a virtual object corresponding to the marker can be read. For example, a marker a1 corresponds to a virtual object b1, model data of the virtual object b1 can be read after the first terminal device identifies and obtains identity of the marker a1, based on the corresponding relationship between the marker a1 and the virtual object b1.

The specific method for identifying and tracking the marker to obtain the position and pose of the first terminal device relative to the marker and the identity of the first terminal device is not limited in the present disclosure.

Wherein, the first virtual object corresponding to the first terminal device can be superimposed and displayed near the marker, and may also be superimposed and displayed on the marker.

In one embodiment, the first terminal device may determine a position coordinate of the first virtual object that needs to be superimposed and displayed relative to the first terminal device in real space according to a preset position of the first virtual object relative to the marker, and the first spatial position of the first terminal device relative to the marker, wherein the marker is used as a reference, and convert the position coordinate into a rendering coordinate in the virtual space, the rendering coordinate is configured to indicate a display position of the first virtual object in the virtual space.

At block S430, receiving interaction data sent from a second terminal device, the interaction data includes data of a second virtual object and a second spatial position of the second virtual object relative to the marker.

In order to realize interactive display between the first terminal device and the second terminal device, the first terminal device can display the first virtual object and the second virtual object corresponding to the second terminal device at the same time. The first terminal device can be connected with the second terminal device, the second terminal device can send the interaction data of the second virtual object to the first terminal device in real time, the interaction data is configured to display the second virtual object corresponding to the second terminal device in real time in the first terminal device. Wherein, the interaction data can include data of the second virtual object and the second spatial position of the second virtual object relative to the marker. Correspondingly, the first terminal device receives interaction data sent from the second terminal device, and determines a position relation between the second virtual object and the first terminal device according to the second spatial position of the second virtual object relative to the marker, which is contained in the interaction data.

In some embodiments, the data of the second virtual object can be model data, the model data can be configured to establish and render a model of the second virtual object, and can include colors, apex coordinates in a 3D model, etc., which are configured to establish the model corresponding to the second virtual object. For example, when the second virtual object is a colored line segment, a 3D point queue (a plurality of point coordinates in display space) of the line segment, a thickness of the line segment, a color of the line segment, and the like can be used as the model data.

At block S440, determining a second display position of the second virtual object in the virtual space, according to the first spatial position and the second spatial position.

The first terminal device may determine a position coordinate of an area where the second virtual object is superimposed and displayed in real space relative to the first terminal device according to the first spatial position of the first terminal device relative to the marker and the second spatial position of the second virtual object relative to the marker, wherein the marker is used as a reference, convert the position coordinate into a rendering coordinate in the virtual space, and thereby obtain the second display position of the second virtual object in the virtual space.

At block S450, generating the first virtual object according to the first display position, and generating the second virtual object according to the data of the second virtual object and the second display position.

In one embodiment, the first terminal device can read data of the first virtual object, and render at the first display position in virtual space to generate the first virtual object. The first terminal device utilizes data of the second virtual object of received interaction data sent from the second terminal device and renders at the second display position in virtual space to generate the second virtual object. The first terminal device displays the first virtual object and the second virtual object at the same time through the display unit, and a user can observe corresponding positions where the first virtual object and the second virtual object are superimposed and displayed in real space through the first terminal device.

When a position and/or a pose of the first terminal device relative to the marker changes, the displayer virtual object changes correspondingly. For example, when the first terminal device goes away from a position of a virtual object in a real scene, the displayed virtual object becomes smaller; when the first terminal device approaches a position of a virtual object in a real scene, the displayed virtual object becomes bigger.

The first terminal device, at the same time of displaying the first virtual object and the second virtual object, can send interaction data corresponding to the first virtual object to the second terminal device, the interaction data corresponding to the first virtual object can include data of the first virtual object and a spatial position of the first virtual object relative to the marker. The second terminal device may also display the second virtual object and the first virtual object corresponding to the first terminal device at the same time according to received interaction data corresponding to the first virtual object sent from the first terminal device.

In some embodiments, there can be a plurality of second terminal devices. The first terminal device can display the first virtual object and the second virtual object corresponding to each second terminal device at the same time and thereby realize augmented reality display and interaction among a plurality of terminal devices.

The interactive method provided by this embodiment of the present disclosure can realize interactive display of virtual objects between the first terminal device 100 and the second terminal device 200, and thereby realizes interactive display between the two terminal devices.

In the interactive method provided by this embodiment of the present disclosure, the first terminal device determines the display coordinate of the first virtual object in the virtual space according to the first spatial position relative to the marker, determines the display coordinate of the second virtual object in the virtual space according to the second spatial position of the second virtual object relative to the marker sent from the second terminal device, and synchronously displays the first virtual object and the second virtual object in combination with data of the second virtual object, thereby realizing interactive display between devices and enhancing interaction between users in augmented reality.

FIG. 6 shows a flow chart of an interactive method provided by another embodiment of the present disclosure. The method may be performed by the second electronic device, and the method may include actions/operations in the following blocks.

At block S610, obtaining a first spatial position of a first terminal device relative to a first marker.

In some embodiments, the marker can include a first marker and a second object. When the first and second terminal devices realize interactive display, the first terminal device can identify and track the first marker to obtain a spatial position of the first terminal device relative to the first marker, and the second terminal device can identify and track the second marker to obtain a spatial position of the second terminal device relative to the first marker. The first marker and the second marker can be the same marker, and may also be different markers.

When the first terminal device and the second terminal device are located in different actual scenes, the first terminal device and second terminal device can correspond to different markers and can establish remote communication connection; the first and second terminal devices can identify the corresponding markers respectively to realize interactive display.

At block S620, determining a first display position of a first virtual object in virtual space according to the first spatial position.

At block S630, receiving interaction data sent from a second terminal device, wherein the interaction data includes data of a second virtual object and a second spatial position of the second virtual object relative to a second marker.

The second terminal device can obtain a second spatial position of the second virtual object relative to a second marker, and send interaction data including the second spatial position of the second virtual object relative to the second marker and data of the second virtual object to the first terminal device. Correspondingly, the first terminal device receives the interaction data including the data of the second virtual object and the second spatial position of the second virtual object relative to the second marker.

At block S640, converting the second spatial position of the second virtual object relative to the second marker into a third spatial position of the second virtual object relative to the first marker.

When the first terminal device obtains the second spatial position, it can convert the second spatial position, take the first marker as a reference, and obtain a third spatial position of the second virtual object relative to the first marker. As one way, the second marker can be equated as the first marker, and the second spatial position can be directly used as the third spatial position of the second virtual object relative to the first marker.

At block S650, determining a second display position of the second virtual object in virtual space, according to the first spatial position and the third spatial position.

After obtaining the first spatial position and the third spatial position, the first marker can be used as a reference so as to obtain a position of the second virtual object relative to the first terminal device, that is, obtain a position coordinate of the second virtual object that needs to be superimposed and displayed in real space, and thus the position coordinate is converted into a rendering coordinate in virtual space of the first terminal device so as to obtain the second display position of the second virtual object.

At block S660, generating the first virtual object according to the first display position, and generating the second virtual object according to the data of the second virtual object and the second display position.

In some embodiments, when the first and second terminal devices are located in different scenes, the situation that a spatial position of the first terminal device relative to the first marker is the same as a spatial position of the second terminal device relative to the second marker may occur; at this time, a spatial position of the second virtual object relative to the second marker can be adjusted so as to prevent the situation that the first virtual object overlaps with the second virtual object. The first terminal device can determine whether the first spatial position of the first terminal device relative to the first marker and the second spatial position of the second terminal device relative to the second marker belong to the same area. In one embodiment, the first marker can be used as a reference to divide a plurality of different areas, the different areas can correspond to different orientations of the first marker, for example, when the first marker is taken as a reference, if the first marker is rectangular, orientations corresponding to four edges of the first marker can correspond to different areas respectively; if belonging to the same area, the first terminal device can adjust a spatial position of the second terminal device relative to the second marker to obtain an adjusted spatial position of the second terminal device relative to the second marker, such that the adjusted spatial position and the first spatial position are located in different areas; and then convert the second spatial position of the second virtual object relative to the second marker based on the adjusted spatial position to obtain a third spatial position of the second virtual object relative to the first marker, and thereby determine a second display position of the second virtual object in the first terminal device. In one embodiment, adjusting the spatial position of the second terminal device relative to the second marker can be mirror transformation for the spatial position of the second terminal device relative to the second marker, such that the spatial position of the second terminal device relative to the second marker is opposite to the previous position, and thereby prevent the situation that the second virtual object and the first virtual object coincide with each other or are displayed at the same side of the marker from occurring and ensure remote interaction.

In one embodiment, the terminal devices can also be located in the same scene, each terminal device corresponding to one marker respectively, and the respectively corresponding markers are different; each terminal device identifies a corresponding marker, can obtain identity corresponding to the marker, and thereby obtain a corresponding virtual object according to the identity. For example, a first virtual object corresponding to the first terminal device and the first marker can be a weapon A, a second virtual object corresponding to the second terminal device and the second marker can be a weapon B, and the first and second terminal devices can cooperatively display the weapon A and the weapon B, and perform interaction.

Remote augmented reality interaction display among a plurality of terminal devices can be realized in the present disclosure, such that the purpose of interactive display can still be realized when the terminal devices are located in positions that are distant from each other.

The interaction data sent from the second terminal device further includes operation data for the second virtual object. The operation data refers to control data for the second terminal device to control the second virtual object according to operation instruction of users, and can include data such as position changes, action pose changes, morphological changes of the second virtual object, which are not limited.

A user can control the second virtual object via an interaction device, the second terminal device generates operation data according to control operations, the second virtual object can perform corresponding changes and display according to the operation data, at the same time, the first virtual object can also perform corresponding changes and display according to the operation data of the second virtual object. The first terminal device can obtain response data of the first virtual object according to the operation data of the second virtual object, wherein the response data refers to generated data of the first virtual object in response to the operation data of the second virtual object, the response can be an effect change of a pose, a position, a model color, a size, etc., and is not limited herein.

In some embodiments, a corresponding relationship between the operation data and the response data can be stored in the first terminal device; after receiving the operation data, the first terminal device can read corresponding response data according to the corresponding relationship. For example, the first virtual object is a wild boar, and the second virtual object is a shotgun, when the operation data of the second virtual object is pose data of the shotgun toward a wild boar and action data of pressing a trigger, the response data of the first virtual object is rendering data of the wild boar being injured and bleeding.

At block S770, rendering the first virtual object according to the response data.

After obtaining the response data of the first virtual object, the first virtual object can be re-rendered according to the response data, such that effect of the first virtual object can be displayed corresponding to the response data. In the aforementioned example, the obtained response data is rendering data of the wild boar being injured and bleeding, effect of the wild boar being injured and bleeding is rendered according to the rendering data, such that a position on the body of the wild boar toward the shotgun displays the effect of being injured and bleeding.

In some embodiments, the first terminal device, when receiving operation data for the first virtual object, can send the operation data to the second terminal device; the second terminal device obtains response data corresponding to the second virtual object, and renders the second virtual object.

In some embodiments, the first terminal device, after obtaining the response data corresponding to the operation data of the second terminal device, may also render and display the first virtual object in combination with the position and pose data of the first terminal device or operation data which is input by a user and input aiming at the first virtual object. In some embodiments, a user can operate the first virtual object, the first terminal device can obtain an operation signal of the user for the first virtual object, and can re-render the first virtual object according to the operation signal.

In some embodiments, when the data of the second virtual object includes the operation data, the first terminal device can display the effect corresponding to the operation data, and the effect can be embodied in the first virtual object and the second virtual object. The first terminal device can re-render the second virtual object according to the operation data for the second virtual object, such that the displayed second virtual object is synchronous to the second terminal device, and re-determine the display coordinate of the second virtual object in the virtual space based on the operation data, wherein the operation data can include data such as pose changes, action releases, position movements of the second virtual object. For example, when the first virtual object is a person 1, the second virtual object is a person 2, and the operation data includes pose data of a hand of the person 2 toward the person 1, application data of a pushing action, and position movement data of a movement towards the direction of the person 1, a display coordinate of the person 2 offsets towards the direction of the person 1 from a previous display coordinate, and display coordinates of parts of a body of the person 2 correspond to the above pose data and action application data.

In some embodiments, the first terminal device can re-render the first virtual object according to the operation data for the second virtual object, that is, according to the second virtual object data such as pose changes, action releases, position movements, and the like in the operation data, determine effect of the second virtual object affecting on the first virtual object, and determine the display coordinate of the first virtual object in display space according to the effect. In some embodiments, the first terminal device can determine whether the first virtual object and the second virtual object meet predetermined preset rules according to the first display position of the first virtual object and the second display position of the second virtual object. Wherein, the preset rules can be whether positions coincide, whether a distance therebetween is less than a certain distance, whether a distance therebetween is larger than a certain distance, whether positions are adjacent, and the like. Specific preset rules are not limited in the present disclosure, and can be determined according to actual requirements.

When the first virtual object and the second virtual object meet a preset rule, effect corresponding to the present rule can be added into the first virtual object and the second virtual object, so as to display the effect corresponding to the preset rule. As one example, rendering data of the effect corresponding to the preset rule can be read, and the first virtual object and the second virtual object are rendered according to the rendering data, such that the effect is added into the first and second virtual objects.

For example, the first virtual object is the person 1, the second virtual object is the person 2, the preset rule is that the person 1 and the person 2 superimposed and displayed in the real space are adjacent to each other, and the effect corresponding to the preset rule can be that the person 1 and the person 2 perform an action of shaking hands. When determining that positions of the person 1 and of the person 2 are adjacent according to the display coordinates of the person 1 and of the person 2, effect of the action of shaking hands can be rendered on the person 1 and the person 2, and a user can observe that the person 1 and the person 2 shake hands.

In some embodiments, the second terminal device also displays both the first virtual object and the second virtual object. The first terminal device obtains a fourth spatial position of the first virtual object relative to the marker, and sends data of the first virtual object and the fourth spatial position to the second terminal device; the second terminal device can generate the first virtual object according to the data of the first virtual object and the fourth spatial position, and display the first virtual object.

The terminal device can generate and display virtual content in virtual space according to the display position and the rendering data. A user can observe display effect of the virtual content superimposed with a real scene via a wearable terminal device such as a head mounted display. Since the rendering data rending virtual content is model data of virtual content obtained after corresponding effect is applied in the virtual content, the rendered and displayed virtual content can present the corresponding effect.

In some embodiments, when spatial positions of terminal devices relative to the target marker are different, angles and positions of their displayed virtual content are different too. For example, the virtual content is an animal model, positions of two terminal devices relative to the target marker are in an opposite state, one terminal device can display a front view of the animal model, and the other terminal device can display a back view of the animal model.

Referring to FIG. 11a , in a scene, virtual content can be a virtual game object 1100 in a game, such as a monster; both a first terminal device 1101 and a second terminal device 1102 display the virtual game object 1100 and a hit point associated with the virtual game object 1100. Since positions of the first terminal device 1101 and of the second terminal device 1102 relative to the target marker 1110 are different, angles of respectively displayed virtual content will also be different. An interaction display method provided by one embodiment of the present disclosure can enable a plurality of terminal devices to display effect corresponding to operation data of all terminal devices on the virtual game object in real time.

A terminal device, after obtaining the response data from the server, can render the virtual content according to the response data and update display of the virtual content, the updated virtual content can present corresponding change effect, thereby realizing operation for the virtual content. For example, the operation data is operation data for adjusting colors of virtual content, and the response data is data for changing the colors of the virtual content.

At block S1240, updating displayed virtual content according to the spatial position and response data.

The terminal device determines a display position of the virtual content according to the spatial position relative to the target marker, and renders the updated virtual content according to the response data received from the server, such that the displayed virtual content presents corresponding effect. Since the response data is generated according to obtaining the operation data of the terminal device in real time by the server, virtual content displayed by a plurality of terminal devices in a system can be kept being consistent.

The method can synchronize response data obtained by the server according to operation data obtained by a plurality of terminal devices in real time during a process of synchronously displaying virtual content by the plurality of terminal devices, and render updated virtual content with effect corresponding to the response data, such that all terminal devices synchronously update the displayed virtual content.

In some embodiments, the terminal device can generate an obtaining request configured to obtain virtual content data corresponding to the identity according to identity of the marker target object, and send the obtaining request to the server. The server can return virtual content data corresponding to the identity to the terminal device. Identity of different target markers can correspond to different virtual content, and the terminal device can display different virtual content by identifying different target markers.

At block S1360, rendering virtual content according to the spatial position and the virtual content data.

The terminal device can display virtual content according to the spatial position of the terminal device relative to the target marker, and virtual content data obtained from the server. In some embodiments, virtual content data obtained by the terminal device can be original content, the original content means virtual content of any terminal device which is not displayed or interacted; and may also not be original content, that is, virtual content which has already been displayed or interacted in other terminal devices.

In some embodiments, the terminal device obtains virtual content data corresponding to identity of the target marker from the server, and can determine whether the virtual content data is original content. When the obtained virtual content data is original content, it indicates that there is not any other terminal device displaying or interacting the virtual content, that is, the terminal device is the first device performing interactive display for the virtual content; the terminal device can display relevant prompt information to prompt a user whether to generate a virtual interaction mode, wherein, the virtual interaction mode can refer to a mode performing interactive display for virtual content corresponding to identity. After the terminal device displays the prompt information, first instruction configured to instruct generating the virtual interactive mode can be detected. When the first instruction has been detected, it indicates that a user of the terminal device needs to generate the virtual interaction mode, that is, generate interactive display for the virtual content, therefore, virtual content can be generated and displayed according to the spatial position of the terminal device relative to the target marker and the obtained virtual content data, and the terminal device can perform interaction operation with the virtual content. When the virtual content data is original content, the virtual content data can be original model data of the virtual content, therefore, virtual content can be rendered according to the original model data, and superimposed and displayed in real space. After the terminal device creates the virtual interaction mode, it can wait other terminal devices to join the virtual interaction mode, to realize common interaction for virtual content.

In some embodiments, when the obtained virtual content data is not original content, it indicates that there has already been another terminal device displaying the virtual content corresponding to the identity, that is, there has already been another terminal device generating a virtual interaction mode. The terminal device can display relevant prompt information to prompt a user whether to join the virtual interaction mode. At this time, second instruction configured to instruct joining the generated virtual interaction mode can be detected; when the second instruction has been detected, it indicates that a user corresponding to the terminal device needs to join the virtual interaction mode, and the virtual content can be commonly interacted and synchronously displayed according to the spatial position of the terminal device relative to the target marker and the obtained virtual content data. When the virtual content data is not original content, the virtual content data can be current model data of virtual content, therefore, current virtual content can be rendered according to the current model data, and superimposed and displayed in real space, thereby realizing synchronous display of virtual content which has already been displayed on another terminal device of the virtual interaction mode at present.

In some embodiments, the terminal device can send information carrying a terminal identification of the terminal device to the server; the server can establish a corresponding relationship between the terminal identification and the identity of the marker, or establish a corresponding relationship between the terminal identification and the virtual interaction mode, according to the terminal identification. By establishing the above corresponding relationship, when realizing data synchronization of a plurality of terminal devices, the server can be enabled to synchronously send virtual content data to all terminal devices belonging to the same virtual interaction mode according to the terminal identifications.

In a scene, the virtual content is a virtual game object, such as a monster. When the terminal device enters this game, the virtual game object can be original content of a new game entered by the terminal device, and may also be non-original content of a game which has already been performed by another terminal device. When prompting a user whether to generate or join a game and receiving relevant instruction input by the user, the terminal device preliminarily displays corresponding virtual content according to the virtual content data and the spatial position relative to the marker; in subsequent display for the virtual display object, virtual game object data generated according to operation data of a plurality of terminal devices joining the game can be obtained from the server in real time, for example, virtual game object data generated according to struck operations to the monster in the game; the virtual game object is updated in real time according to operations of the plurality of terminal devices for the virtual game object, so as to realize that the plurality of terminal devices real-timely and synchronously present effect corresponding to operation data of all terminal devices on the virtual game object. For example, when any terminal device obtains data of striking the monster in the game, each terminal device in the system can real-timely present the effect of virtual content, thereby synchronously presenting the effect of the struck monster, enabling a plurality of users to join the game commonly, and improving interaction interest.
